The build of the F3 hovercraft was started from a basic fibre glass shell purchased from BBV Hovercraft .
 
After this, we design the layout of the hovercraft. The team fabricate our own engine and fan frames, then engineer the shaft - drive system to run the lift fan. We have also adapted our ex-motorcycle engine to run with no gears. This engine drives both fans straight off the back of the crank. With this set up, we develop an all-round efficient hovercraft. The engine we use is a Honda RS 250 . This is from a grand prix racing motorcycle. With the modifications we have made, the horsepower has been increased from 85bhp to around 100bhp.
The drive from our modified engine is then transferred to the fan by a Centa coupling; this coupling takes the 13,000rpm produced while bouncing around on both land and water.
The whole process is a combined family effort, with myself and my dad undertaking the main design and construction. Completion of a new hovercraft takes around 6-8 months of long days and nights. As well as financial help we also receive help from Hanson Building Products with lathe machining work.
